!!!!Sample Code:
        public static SERVICE_STATUS_PROCESS QueryServiceStatusEx(IntPtr serviceHandle)
        {
            IntPtr buf = IntPtr.Zero;
            try
            {
                int size = 0;

QueryServiceStatusEx(serviceHandle, 0, buf, size, out size);

buf = Marshal.AllocHGlobal(size);

if (!QueryServiceStatusEx(serviceHandle, 0, buf, size, out size))
                {
                    throw new Win32Exception(Marshal.GetLastWin32Error());
                }

return (SERVICE_STATUS_PROCESS)Marshal.PtrToStructure(buf, typeof(SERVICE_STATUS_PROCESS));
            }
            finally
            {
                if (!buf.Equals(IntPtr.Zero))
                    Marshal.FreeHGlobal(buf);
            }
        }
